Hello everybody

I have been using SQL Server 2000 for my database needs some time now. Recently, I`m trying to develop a .NET Compact database application on an iPaq (Windows Mobile 2003).
I know that I need the SQL Server 2000 CE edition. Is this just an upgrade to SQL Server 2000 which I can download or do I need to purchase a new DBMS?

thx, in advance
